Also thought I would share this about securing your photos
VERY IMPORTANT!! Artists and photographers. Make sure you set your privacy settings within Google Photos (ie. Picasa) to keep people from ordering prints of your images or downloading you images.
1. Click on Photos at the very top in the black nav bar.
2. Little Gear in the far right very top corner is your settings link for whichever aspect of G+ you are in.
3. Photo Settings > Privacy and Permissions
4. Unclick Order Prints and Download my Photos
5. Save Changes.
